` l `nulcnovrzn sn'nmnnm Damme-Ansmann `The Schedule; referred to lnthese Letters Patent and making part o1 the eamo.

` Be it known that I, THOMAS F. ROWLAND, of Greenpoint, in the county ofKings, and State of New York, have invented a new and useful Improvementin Submarine Drilling-Apparatus, of which vthe following is a full,clear, and exact description, reference 4.beinghad to the accompanyingdrawing,

Aforming part of this epeciiication, and in which-- i Figure 1represents an eleva-tion of myimproved Figure 2, a sectional or stand. iM o Similar letters of reference indicate corresponding parts. i

inverted 1an of the drill-frame First, in anovel construction ofdrill-frame, or stand, or, as it may be termed,jworking-platform, byprovidf ing or forming itwithtelescopic legs, made up of tubes andpluugers, and connected with `suitable hydraulic attachments or devicesfor forcing water into the logs v for the proper support of the platformat different elevations, according to the depth of the water, and ltoadjust the legs `or their plungers to' a firm bearing i on the rock tobe drilled.

Secoudlygthe invention consists' in a combination of a floatingsteam-pump, or engine, a separate waterpressure engine, carriedby anindependent fixed 'ame, or support, an elastic tubular counectiomwherebythe latter engine is driven by Water forced, or conveyed under pressurefrom the former, anda drill operated by the stationary or non-floatingengine'.

Thirdly, the invention consists in a combination of a floatingsteam-pump, a Water-pressure engine for o operating the drill, anindependent orf'stationary plato form, provided with telescopic legs forcarrying said engine, and flexible `tubular connections between theiloating steam-pump, auxiliary engine, and platform.

`or its legs, whereby said pump serves to convey water both for drivingthe drill, through the independent or water-pressure engine, adforadjusting or setting the platform, through its telescopic legs, on'andata suita- Vble height above the rock to be drilled In the accompanyingdrawingp A represents a boat, float, or scow, which serves-to carry a`steam-pump, B, and boiler for working the same. Said float, or scowalso should be of sufficient `dimensions to carry to and from the vplaceof work,

the remainder of the apparatus `'or'working-platform', with itsattachments and derrick, for lowering and littscow. i

The drill-frame is made up of a table,0, preferably fitted with `one ormore leaves a, to admit of its extension, and facilitate carriage, andtelescopic legs formed of tubes D D, and rods or plungers E E fittingfreely within the tubes, and arranged to project throughstuiiing-boxes'in the lower ends of the latter, thewhole beingsta ed bybracesb'b.

On the table C is erecte a rotary, or other suitable water-pressureengine, F, which serves to oprate, through appropriate gear, the drillG. A i

This engine is workedby water conveyed or forced under pressure to itfrom the steam-pump F,-by or through a hose, or flexible tube H, whichestablishes connection between Vsaid pump and engine.

Arranged below the table O is a circular pipe, I, having a branch, o,that is also connected by a hose, or dexible tube, J, with thesteam-pump, said branchv being fitted with a. valve, or cock, d, forvturning on' and oi the supplyof water from the pump'. Y

This pipe I, which forms a distributing-conduit, connects by branches ee, having cocks, or valves ff, with the tubes D D, lnear their tops,which are closed.

` From this "deseriptior, it will be seen that onthe drill frame, orstand being lowered by the derri'ck to its place on the rock to bedrilled, and the :cocks f f opened, the working-platform, or table'Omay, on setting the steam-pump B in motion, be elevated or set to anydesired height byhydranlic pressure or action, as caused by forcingwater into the tubes D D, and pressure of the same on or against theupper ends of y, the plungers E E. y l* In thisway, or by these means,the working-platform is made to rest upon aA series of columns of waterand by opening or closing the cocks f f, or certain of them, and openingor closing water-discharge taps to the legs for lowering them, it may beadjusted or set vto any desired height or level, and a 'drin supportsecured to the drill-frame, or stand on the rock.

This being done, communication, through a suitable valve, is opegedbetween the steam-pn mp B and waterpressure engine F, which sets inmotion the drill G.

'Ihus the pump' B serves to set and adjust the working-platform, andindirectly, that is, through the engine F, to work the drill.

The independent character, however,"of the working-platform andenginecarried by it, relatively to the floating steam-pump, and connectiontherewith by flexible tubes, is an Vimportant feature, for such notonly'secures to said 'platform and engine a fixed, or

drilling, while the floating pump` is free .fall with the undulations onthe surfaceof the water, butthe engine F may be workedundercircumstances and conditions that would be neither safe norpracticable were it the primary driving-power; thus it and the-working-platform may be under water without impairparatus, andthefloating engine, onpump B, which is the primary power, he at any desireddistancefrom thedrill-frame, er stand, and be operated with equal beingdone, and totally independent, as it were, of the latter. y

yWhatis here claimed, and desiredto be secured b v- Letters Patent, 1s'

,1. The telescopicdrlll-frame, forming, or carrying a stationarycharacter, that facilitates the operation of to rise and ing o r finterfering with the general action of the apfacility under the mostvaried .conditionsof the work working-platform, and made up of tubularlegs and plungers ory rods projeeting therethrough, in oombination withhydraulic attachments, or devices for forcing water, under the controlof suitable valves, into the legs, substantially as and for the purposeor purposes herein set forth.

2. The combination of a oatng steam-pump, or engine, an aiiliarywater-pressureengine, carried by an independent stationary frame, orsupport, a flexible tubular connection, for transmitting power, throughhydraulic pressure, or action from the one engine to the other, and adrill operated by vthe auxiliary, or stationary engine, essentially asspecified.

3. The combination of the ioating steam-pump B, the stationarywater-pressure engine F, for operating the drill, flexible tubularconnections H J, and a working-platform, made up of a table andtelescopic legs, for action, substantially as described. 4
